The Australian supermodel posed in the buff for photographer Chris Colls, who shared that sexy snap you see here on Instagram. The former Victoria's Secret Angel, 30, has posed for Colls previously ... and has always looked super sultry while doing so. In this particular pic, Kerr is totally topless and bottomless, save for a very deliberately placed white sheet near her lady bits.

It's the third time in as many months that Kerr has showed off what her momma gave her. She bared her breasts for V magazine in August, followed by posing in nothing but a pearl g-string for Interview in September. She's also gracing the January/February 2014 cover of the Australian edition of Harper's Bazaar, with shots taken by Terry Richardson. Check out those red, red lips too. Ay caramba!
